    It's a management UI where concerns were raised that it downloads from third party server. However this issue was handled very fast and code was removed: https://github.com/swoole/swoole-src/issues/4434

    FOMO is created by Iranian developer amirfaramarzi. This framework sits on top of the asynchronous event driven framework swoole that creates insane levels of performance out of apps (we're talking Go/Rust level of performance)! Check out the performance on the Web Frameworks Benchmark.
  • Why is Apache clinging to OpenOffice's corpse?

    > I tend to install FOSS because imo they are more "future-proof", but some of them are developed by companies (e.g., Fedora Linux) and that makes me wonder if they're truly future-proof.

    The story of CentOS should be telling that, no, many pieces of software that are backed by a company will not be future-proof and will probably experience certain changes as a consequence of that, be it being transformed to better fit corporate goals (CentOS Stream), or being retired eventually so the company may focus on something else (Atom), or will just be left to slowly rot over time as happens with most code (OpenOffice).

    Then again, it's not like open source projects are that future proof or safe from "drama" either - for example, the Lubuntu project has 2 homepages for no reason: the official one at https://lubuntu.me/ and some other one that serves old versions and is not trusted by my ad blocking solution https://lubuntu.net/

    There are also cases, when open source projects experience fragmentation like happened with Gogs https://gogs.io/ and Gitea https://gitea.io/en-us/ and sometimes there are cases where particular individuals simply cannot work together and as a consequence pretty much the same happens, as was the case with Swoole and Open Swoole: https://github.com/swoole/swoole-src/issues/4434

    Treat most pieces of software that you use as if they might not be there in a year.

  • Take your Serverless Functions to new speeds with Appwrite 0.13
    3 projects | dev.to | 7 Mar 2022
    To allow for synchronous execution and prioritize speed, we decided to depart from the task-based system that most of our workers use and instead create a new component to Appwrite called the executor. The executor would handle all orchestration and execution responsibilities and remove the Docker socket from the functions worker. The executor is an HTTP Server built with Swoole and Utopia using various Appwrite libraries to interact with the database.

    Swoole will be shipping something really-really cool that is it's own CLI. You can checkout the development at https://github.com/swoole/swoole-cli and you can start playing with it using the pre-compiled binary distributed under Swoole's releases at https://github.com/swoole/swoole-src/releases/tag/v4.8.7.

    > modern times to run php, people would use php-fpm with nginx, it is running multiple worker (single) process, so why would anyone [2], [3] wants multi-core coroutines in it? What does it even mean?

    Not everyone does. There's also https://reactphp.org (which is an event loop runtime, similar to Node), and https://amphp.org (also event loops), and Swoole https://github.com/swoole/swoole-src (coroutine runtime, similar to Go).

    Fibers are basically an API that event-loop runtime libs can use so that userland code doesn't need to use promises or generators to run non-blocking operations.
